I ICE-MAKING MACHINE.

To all whom it inay concern:

Be it known that I, JOHN SOUTHER, a citizen of the United States, residing at Newton,

in the county of Middlesex and State of .Massachusetts, have invented new and useful Improvements in Ice-Making Machines, of which the following is a specification."v

This invention relates to ice-making ma chines, and the object is to provide a machine having a plurality of. receptacles adapt-' ed to contain water intended to be frozeninto blocks, said machines so constructed and arranged that said receptacles are surrounded on all sides by air, so that all sides are subjected to a like temperature, said receptacles so shaped that ice which forms within them may be easily freed and dis-- charged therefrom.

The invention consists in aplurality of receptacles having upwardly-diverging sides,

said receptacles rigidly connected together in arow and pivotally mounted upona stationary frame.

The invention finally consists in the combination and arrangement of parts set forth in the accompanying specification and par? ticularly pointed out in the claims thereof.

Referring to .the drawings, Figure 1 is a plan view of my improved ice-making ma-' plurality of receptacles 7-, 8, 9, and 10 are rigidly connected at their adjacent edges and are further strengthened by longitudinal strips 11 11 at their upper edges and strips 12 12 alon 'their lower edges, said strips being'riveted to said receptacles. The receptacles 7, 8, 9, and 10 are pyramid frustums. In other words, they have upwardly-diverging sides and are preferably formed of sheet metal. The frames 6 6 are provided at their upper edges with jaws. 13 13, in which are journaled shafts 14 and 15. The shaft 14 is provided with a flange 16, riveted to the receptacle 7, and the shaft 15 is provided with a flange 17, riveted to the receptacle 10. A handle 18 is fast to the shaft 15.

The median pivotal line a a is preferably Specification of Letters Patent.

located above and closely adjacent to the center of gravlty of the receptacles 7, 8, 9,

and 10. A rod 19, extends longitudinally of the receptacles 7, 8 9, and 10 and is fastened at either end to the frames 6 6. A hook 20 ispivoted to the receptacle 10 andis adapted to engage the rod 19, and lock said receptacles in their horizontal or normal position. When it is desired to rock said receptacles upon their pivots, the hook 20 is disengaged from the rod 19 and the operator by grasping the handle 18 may rock said receptacles on their pivots to the position indicated in dotted lines, Fig. 3, to discharge their contents. The receptacles 7, 8', 9, and 10 are intercommunicating by means of passages 21 21 21, formed in their upper adj acent edges.

When it is desired to make ice in the receptacles 7, 8, 9, and 10, they may be filled with water, said water coming to a common level in all of said receptacles by reason of the connecting-passages 21. Said receptacles are then exposed to the action of the atmosphere below the freezingpoint, thereby causing said water to be congealed or frozen into blocks.

of thefact that the median pivotal line a a is go located slightly above their center of gravity have no tendency to tip over of their own When this has been accom-' plished, the operator releases the hook 20 weight; but said median line being located closely adjacent to said center of gravity the operator may'with perfect ease tip them by moving the handle 18.

One of the chief advantages secured by the invention hereinbefore described is that the same may be manufactured for use by private individuals, so that they may during the cold season prepare sufficient ice for their own consumptionfor the whole year,

the ice thus prepared being stored in a suitably-constructed ice-house of sufficient size to hold a year's supply.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, 1s-
